The test bench is designed to evaluate air-oil mist filtration performances of the filtration elements and vessel during time. The test bench has been designed to allow the testing of two different arrangement for the filter:
To reproduce the real working conditions of the tested filters, the test bench has been designed to generate an oil mist that is dispersed into the air stream using an atomizer nozzle driven by compressed air.
The test bench has all the necessary equipment and instrumentations to allow the reliability and repeatability of the test. The test bench allows the remote control of the tests using the Control System that performs all the automatic controls, the main control loops are:
The control System also performs the safety control loops in case of any malfunction, stopping the test and bringing the test bench in a safe state.
The test bench has air sampling points allowing the characterization of air-oil mist and the determination of number and mass separation efficiency.
Evaluable variables are:
